  • the rotational supporting means 60 includes the connecting bar 90b, fixing bar 92b, moving bar 98b, supporting bar 110 sequentially connected in a line
  • the treatment board 46 is installed at the fixing bar 92b with the first link mechanism 42a
  • the microscope 48 is installed at the moving bar 98b with the second link mechanism 42b
  • the monitor 50 is installed at the supporting bar 110 with the third link mechanism
  • the treatment board 46, microscope 48 and monitor 50 all move synchronously when the rotational supporting means 60 is rotated.
  • the supporting bar 110 can be turned to a predetermined angle around the moving bar 98b by releasing the control knob 98d, which fixes the lower vertical portion of the supporting bar 110 and the upper portion of the moving bar 98b. Also, the supporting bar 110 can be stopped at a predetermined height level when the control knob 98d is tightened. As a result of the aforementioned structure, the monitor 50 connected to the supporting bar 110 with the third link mechanism 42c and the microscope 48 connected to the moving bar 98b with the second link mechanism 42b can be positioned to face each other around the patient rotation chair 30.
  • the supporting bar 110 illustrated in the fifth embodiment is more cost-effective and has a simpler structure than the second embodiment of the present invention where the microscope 48 and monitor 50 are respectively supported with the moving bars 98a, 98b.
  • the rotating patient chair mounted with an integrated ear diagnosis and treatment unit described in accordance with the first through fourth embodiments of the present invention is constructed with suctioners, treatment board, microscope having a camera, monitor, control box to control devices and treatment tools, so that the monitor and microscope can be positioned in correspondence with the patient's ears anatomically positioned at 180 degrees, to enable the patient to observe all of the treatment processes to his or her ear parts including the thin, dark auditory canals and eardrums, on the installed monitor and to enable the practitioner to explain all of the treatment processes shown on the monitor to the patient and his guardians, thereby improving reliability on the practitioner and the treatment processes and maximizing the treatment effects.
  • diagnosis and treatment processes can be performed on the patient's ears by not letting the practitioner or patient move around but by merely rotating the ear diagnosis and treatment unit, thereby minimizing discomfort and inconvenience to the practitioner or patient, shortening the medical treatment time and minimizing the space of a treatment room occupied by the diagnosis and treatment unit.
